- <i>Background:</i> The opportunistic yeast <i>Malassezia</i> is considered to be one of the factors that can contribute to atopic eczema (AE). Elevated serum IgE levels, T-cell proliferation and positive skin prick test (SPT) and atopy patch test (APT) reactions to <i>Malassezia</i> are found among AE patients. <i>Methods:</i> Sera from 127 AE patients, 14 patients with seborrheic dermatitis (SD) and 33 healthy controls were investigated for IgE and IgG4 to <i>M. sympodialis </i>extract and four recombinant <i>Malassezia</i> allergens; rMala s 1, rMala s 5, rMala s 6, and rMala s 9. In addition, IgG to the recombinant allergens was analyzed. The IgG and IgG4 levels were compared to IgE levels and in vivo reactions (SPT and APT) to <i>Malassezia</i>.<i> Results:</i> AE patients with serum IgE levels >0.35 kU/l to <i>M. sympodialis</i> extract had significantly higher IgG4 levels to <i>M. sympodialis</i> extract than AE patients without detectable serum IgE to <i>M. sympodialis</i> extract, SD patients and healthy controls. Among the AE patients with and without detectable serum IgE to <i>M. sympodialis</i> extract, respectively, there were no differences in IgG4 levels between patients with positive or negative in vivo reactions to <i>M. sympodialis</i> extract. IgG4 to the rMala s allergens was almost exclusively found among patients with IgE to the same allergen. Within the four tested rMala s allergens, most IgG4 reactions were found to rMala s 6, an allergen with homology to cyclophilin. <i>Conclusions:</i> Elevated serum IgG4 to<i> M. sympodialis</i> extract accompanies elevated serum IgE to the extract. This is further confirmed by the association between IgG/IgG4 and IgE to recombinant <i>Malassezia</i> allergens.
